Staple cassette

Abstract

A cassette for pre-formed U-shaped staples comprising a core member formed with a helical rib and a web of pre-formed U-shaped staple elements wound on said core member in helical fashion following the rib formed on said core member. A tape attached to the web serves to apply rotative movement to the core member which moves axially for dispensing of the staples.

What is claimed is: 
     
       1. An improved device for storing and feeding preformed U-shaped staple elements comprising a generally cylindrical core member formed with a helical rib and being movable axially, a web of pre-formed U-shaped staple elements wound on said core member in helical fashion following the rib formed on said core member, said rib having a height and pitch coextensive with the height and width, respectively, of said U-shaped staple elements such that the rib houses the staple elements, and a tape attached to said staple elements, said tape being adapted when pulled to cause rotation of said core member and axial movement thereof to feed said staple elements along a fixed path.
